Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

open access: yesJournal of Anatomy, EarlyView.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change

open access: yesMedical and Veterinary Entomology, EarlyView.
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

The “Pesticide Chip”: Chemical Legacies and Agrarian Futures in Costa Rica

open access: yesAntipode, Volume 58, Issue 2, March 2026.
Abstract For decades, agro‐industrial capital has adopted cascading chemical and biotechnical interventions, or fixes, to secure accumulation through the cultivation of monocrops. We develop a framework that centres on how monocrop‐induced susceptibility to pests and pathogens—and the patchwork of fixes to address these—produces uneven chemical ...
